Former Nairobi County Finance CEC Winfred Gathagu has told the Milimani Anti-Corruption Court that the graft charges facing former Nairobi Governor Mike Sonko were part of a broader plot orchestrated at State House to remove him from office.

Testifying before Milimani Principal Magistrate Charles Ondieki, Gathagu revealed that senior State House officials approached her and other county executives in 2019, urging them to help fabricate criminal charges and support Sonko's impeachment because he was fighting corruption at City Hall. "I and my colleagues from Nairobi County were approached on several occasions by senior officials from State House to assist in conjuring up solid cases against my former boss Mike Sonko for court proceedings, impeachment, and so on," Gathagu testified.

Led in her evidence by lawyers Assa Nyakundi and Elizabeth Ochieng, Gathagu recounted how she became involved in the matter.

She told the court that although she recorded two statements with the Ethics and Anti-Corruption Commission on January 15 and 20, 2020, but she was never called to testify as a prosecution witness.
